FABRICATED WINDOW-SASH MOUNTING.

Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed August 9, 1918. Serial No. 249,053.

To (:ZZ w hom it may concern:

Be it known that I, ARTHURC. Soon], a citizen of the United States, anda resident of the city and county of San Francisco,

State of California, have made a new and useful Inventionto wit,Fabricated Window-Sash Mountings; and I do hereby declare the followingto be a full, clear, conelse, and exact description of the same.

The invention relates particularly to the construction, arrangement andmanner of installing the mounting, and to means for controlling theoperation of the sashes therein.

Among the objects of the invention are to produce a structure of thisnature capable of being fabricated in quantities. and installed withinwindow casings or frames with the minimum'amount of labor and expense,and to provide a sash control of superior merit for the purpose.

In this specification and the annexed drawings the invention isillustrated in the form considered to be the best,-but it is to beunderstood that the invention is not limited to such form, because itmay beembodied in other forms, and it is also to'be understood that inand by the claims following the de scription, it is desired, to coverthe invention in whatever form it may be embodied.

Fig. 3 is a fragmentary detail inside elevation illustrating the pivotaland frictional connection of the support arm with the side of the sash.i r

Fig. 1 is a similar view illustrating the connection of the support armswith the window frame.

Fig. 5 is a similar viewin-front elevation illustrating the resilientpivotal. connection of the sash with the sash guides.

Fig. 6 is a similar view of the same in plantaken from above in crosssection on the line VI-VI, Fig. 5.

In detail the construction illustrated in the drawings includes theconventional window frame composed of the sill 1, the stool 2, the sidejambs 3-3 and the lintel 4, joined in the usual manner to form arectangular frame or casement.

By the present construction and inven tion the sashes and theirmountings may be fabricated in quantitiesand easily installed bymechanics of ordinary skill, with the insurance of perfect operation.This is accomplished by providing the substantially L shaped fixturestrips 5 having the angular extensions 6 thereon. To these strips arerigidly fixed longitudinally as a part thereof the sash guides 7preferably consisting of a length of fiat metal with rounded edges,provided with a suitable weather resisting coating. The strips 5 aresuitably grooved at the lateral edges of the guides 7, to clear thecurled edges 8 of the sliding pivotal shoes 9 slidably engaging theguides 7. The stiles 10 10 of the sash areprovided with spring tensionmembers 11, fixed thereto on opposite sides of the upper corners andterminating with the ends 13 parallel with the sash stiles, at whichpoint they are pivoted at 14 to the pivot shoes 9. The tension of thesespring members at 12 is inward toward the sash so as to pull the strips5 and sash snugly together at the contacting edges 14, see Fig. 6. Boththe upper and lower sashes, if more than one is used, are similarlypivoted at their upper corners, and slidably engage the guidestrips 7. i

The angular extensions 6 of the strips 5 act as stops for the abutmentof the inner face of the sash stiles 10. For the purpose of furtherweather-proofing the joints between the sashes and their mountings Iprovide metal weather strips 15' having angular bent back edges 16toengage a similarly shaped groove in the inner face of the extension 6.The angular edges 16 co6perating with the tapered grooves in the stripstend to pull the strips 5 snugly against the edges of the sashcontributing to the tightness of the joints at 14: as well as at 17,insuring a close, tight, weatherproof fit between the sash and thestrips 5 at all points of contact. These grooves are substantially Vshape to facilitate entrance of the edges 16 thereinto.

The weight of thesashes is supported by the side jambs 3-3.

the support arms 18 pivoted to the sash stiles 10 at or near theircenters on the fixed pivots 19; the opposite ends of the arm 18 arepivoted at 20 to sliding shoes 21, similar in construction to the pivotshoes 9 and similarly engaging the guide strips 7. The pivots 20 may befixedly instead of slidably connected to the guides 7 at the properpoint and under normal circumstances the manipulation of the sash on itspivots 1 1 can be properly adjusted, but such a simple mounting hasproven unreliable incontrol of the device under influence of strong windor other conditions likely to chan e its set position. For that reason Iprefer to inter-pose the sliding shoes 21 which permits the pivot 20 tomove vertically in conformity with the con-- trol link 22 fixedlypivoted at 23 to the guide 7 and to the support arms 18 at 24-,transforming the arm 18 from a simple lever to a compound lever bymoving the fulcrum of the point 20 to the point 24:, the multipliedleverage giving a better control over the operation of the sash throughthe support arms 18 as hereinafter will be described. I

To control the operation of the sash on the support arms 18, I interposethe friction links 25 pivoted at 26 to the sash at a point spaced fromthe support pivot 19, the opposite end of the links being pivoted at 27to the friction slides 28 having their edges crimped around the edges ofthe support arm 18 and adapted to frictionally slide upon the same.

For greater rigidity of the structure and to insure the proper spacingof the pivotal points 19 and 26 I prefer to intcrpose the plates fixedto the sash stiles by the screws 31, behind the rabbet edges 32 thatinclose the support arms 18, the links 22 and 25 and assembledmechanism, so tha they are hidden when the sashes are closed.

Thus assembled a multiplicity of sashes may be combined within a singlemounting fabricated and assembled ready to be forwarded to the point ofinstallation with their working parts in their proper relative positionsand adjustment. It is usual to leave the lower end of the strips 5 alittle longer than specified, so that they may be sawed off and shapedto fit the top surface of the sill 1 as at 83. If exact specificationsare available at the mill even this part of the operation may beperformed at the point of fabrication. The sashes and the assembledmountings are installed within the frame or casement described, byresting the lower ends of the fixture strips 5 on the sill 1 andswinging their tops against the stop 34 on the lintel between 1 Tofacilitate lateral fitting I leave the raised beads 35 on the outersurfaces of the strips 5 which may be easily planed down to accomplishthe approximate fit between the mounting and the jambs 33. Thus insertedwithin the frame the stops 36 and 37 are nailed to the interior of thewindow frame. Thus the installation of the sashes and their mountings iscomplete, and held in permanent assembly with the casement frame betweenthe stops 3%, 34 86 and 37. The beads 35 are trimmed down sufficientlyto allow the necessary play to compensate for expansion and contractionof the structure due to weather changes, at all times allowing freeoperation of the moving parts.

Sashes thus mounted operate substantially as follows: The meeting rails'38-39 are suitably shaped, in the usual manner, to exclude weather andto rest one within the other so that when the sashes are closed theypresent an even plane, or if it is desired the guide strips 7 may beoffset on the strip 5 so as to permit the sashes to overlap at themeeting rails. This, however, introduces complications and is not thepreferred form. WVith the sashes thus assembled and installed andpresumed to be in the fully closed position and it is desired to openthem, the first action is to push outward on the lower rail 40 of thelower sash. This permits the sash to swing outward on its pivots 14causing the pivotal shoes 9 to slide downward on the guides 7, releasingthe meeting rail 39 from the meeting rail 38, the sash assuming anyangle desired by the operator. In similar manner the top sash can alsobe placed at any angle desired. The pivot shoes 9 descend as the angleof the sash approaches the horizontal, at which point continued actionaccomplishes the total reversal of the sash, presenting its outersurface to the interior of the room to facilitate washing.- The lowerpivot 20 of the support arm 18 rises under the influence of the fulcrum24 as the sash opens. The link control 22 performs a valuable functionin controlling the sash, as it transforms what would be a simple pivotalaction at the point 20, into a sliding action accommodated by the shoe21, and causes a pinching or jamming action which must be overcomebefore the sash can move. To further insure the maintenance of thedesired angle of the sash, I interpose the links 25 with thefrictionslides 28, interposing the. same action introduced by the links 22,tending to pinch or jam, and together with the friction exerted by theshoes 28, holding the sash in any set position, yet capable of easymovement at the Will of the operator handling the sash near the bottomrail 40. The link 25 is preferably pivoted at 26 below the pivot 19 forthe reason that the more nearly this link 25 approaches the horizontalangle, the more counter leverage it exerts, to prevent the displacementof the sash from its set position.

The same is true of the link 22 which may be made much longer, but thelengthening of which increases the rise and fall of the fixtures asshown in F 2, any number may be assembled in a single casement frame.The duplex assembly of two sashes assembled between two double fixturestrips 5, as in Fig. 1, illustrates the adaptability of the system.Neither do I wish to be understood as limiting this invention to thespecific form of sash control, as many forms covered by patents in myname and others may be interposed between thesashes and the fixturestrips.

In adapting this invention to steel con struction and to meet otherspecial conditions, modifications within the purview of the inventionare available to those skilled in the art in practising the invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:
